ABSTRACT:
An access device is adapted to facilitate introduction into a body cavity, such as the abdominal cavity, of an instrument having an elongate shaft and a bend in the shaft. The device includes a hub having a wall disposed at the proximal end of a cannula which is configured to extend into the cavity. The hub has a normal configuration with a length and diameter which inhibits passage of the bend of the shaft through the hub, but the wall of the hub is progressively bendable from the normal configuration to facilitate passage of the bend through the hub.
